I've definitely found that four leaf clovers are a lot more common that people think. If you really start to look for them they are pretty much everywhere. Motorcycles on the other hand... I have a hard time with that because while I do think people don't see them, many motorcycle drivers are quite reckless, but it's always the cars fault no matter what because of the stigma. I think it's ridiculous. Trust me, I know car drivers are reckless too, but there is certainly a double standard.
